Erratum to “Long-Term Treatment of Native LDL Induces Senescence of Cultured Human Endothelial Cells”

Figure 2

Senescence induction in HUVECs by long-term treatment with nLDL (0, 2, 5, and 10 μg protein/mL), for up to 9 days. (a) Quantitative assay of SA-β-Gal activity after nLDL treatment; (b), SA-β-Gal activity staining after nLDL treatment. HUVECs were treated with nLDL at the start of each subculture and assayed for SA-β-Gal activity at the end of each subculture. The SA-β-Gal activity was expressed as the generation rate of 4-methylumbelliferone (MU)/μg protein against that of the respective nLDL-untreated group. The dose- and time-dependent differences in SA-β-Gal activity between groups (a) were an alyzed statistically by repeated measures ANOVA assay (). Each nLDL-treated group was also compared with the respective nLDL-untreated group by independent -test (). Each result represents the mean ± SD ().
